SWARTZ CREEK, Mich. (AP) - General Motors says it's spending $10 million to renovate a warehouse and distribution center west of Flint. The Detroit-based automaker said Thursday that improvements to the Swartz Creek Customer Care and Aftersales facility include upgrades to information technology and its paint shop. The administration building also is getting a brick front and expanded lawn with trees. The work is expected to be done by the fourth quarter of this year. GM says the 3.1 million-square-foot center employs about 300 hourly and salaried workers. It distributes more than 9,000 collision parts to GM's 4,300 Chevrolet, Buick, GMC and Cadillac dealers in the United States.
